GRUNDIG Vision II LCD has sound but picture goes into color test

Once warmed up the picture disappears completely then it goes into some sort of color cycle test where the complete picture goes blue, then white, then green, then red. This pattern cycles continuously. The sound remains ok. Turning the set off then on may bring back the picture for a short while, but generally it stays in color test mode

    My TV screen goes white after about ten minnutes of watching.

    I have placed the remote control on Sat/Cab. which has helped but not sure if it cured because the TV did the same thing a couple of nights ago. It used to do this every time that I turned the TV on. Now it just does it when I punch a wrong button or something?

    I have the same problem. My TV screen turns white after about 20 minutes. I have called the technical support for RCA who wanted me to ensure that my TV remote was on Cab/ Sat. I did this a couple of times and it does not fix the problem. The only thing that works is to cut off the set and wait five minutes or more. The you can watch for another 15 minutes or so.

SOURCE: Insignia 26" cycles colors

This is a problem with the switching circuit on the television. The color cycling is a service test pattern for checking the operation of the color circuits on the television. This could be as simple as a cold solder joint on the circuit board or crosstalk on the circuit board or wiring causing the problem. It also could be a problem with a faulty component or the switching control IC. This should be tested in a service center to isolate the problem. The service number for Insignia is 1-877-467-4289. Hope this helps you with your problem. The second problem is not the same as the vertical lines are another problem altogether . This unit need to check for faulty components at a service center. Please call the above number for technical help with you problem. Hope this helps you with your problem.

Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

This could be a reception problem of the cable transmission or the cable box if used. Are you using cable or SAT box. Tv goes to blue screen if signal is weak automatically.

Picture and sound come on picture disappears


There is probably a fault in the video processor, or there is a setting for the user colour temperature that is not properly set. Call the authorized service for advice on how to proceed

Picture goes on and on constantly


I have the same problem. Picture cuts out completely then back on. When I first turn it on, it does this constantly for about 15-20 mins, then about once every 30 mins or so. The sound is fine, but the picture just flashes on and off.

The color is also starting to shift a lot and cannot be fixed by adjusting COLOR-BRIGHTNESS-PICTURE in the video control menu system. Nothing seems to correct this. I've even unplugged the TV over night to see if it needed some sort of reset. Model = KV-20FV12. Purchased in 2004

My connection is a direct cable connection - Comcast cable. Same problem persist while showing a DVD as well.
